(a) FDTD simulation results of transmission spectra through the bare slot antenna with (red) and without (black) PMMA, for L = 200 µm and wgap = 15 µm. (b) Transmission spectra through the hybrid slot antenna with (red) and without (black) PMMA for lNW = 5 µm. (c) Resonant-frequency shift as a function of the total number of AgNWs (NNW). (d) Enhancement factor as a function of wgap for fixed NNW = 80 and lNW/wgap = 1/3. (The solid line is a guide to the eye.).
